The mod is superb, and I'm choosy so it's a compliment worth having. - meanwhile, be aware of this potential fault.

Symptoms : All ai run out of fuel mid-race

On Further Investigation : - All is okay on the latest gem and so on but your track distances on the map and introduction screen (the one in-game) where you choose the number of ai, laps, etc, all read 0 miles.

Where It Can Happen : Monza 10k with 69 mod (unreal but I like it)

Cure: Copy, and paste in, track distance information (no of turns, length of lap, etc) from the general track.ini into the mod's track69.ini -all inside the tracks folder in Sierra.

Other difficulties include:

(i) The cars pit line-up is in the middle of the track, not in the pits

(ii) The usual driving view is lost at the start of the race, with a 'camera on lower nose of car' effect instead, Any cars ahead and to the side may have no rear suspension/wheels or be otherwise 'Maintained by Morecambe and Wise' https://www.youtube....h?v=e-IaYXJrDjo . This interchanges with a rectangular panel of grass as the cars start up and normal service is resumed a few moments later.
